Hi all,
I have a combo-box consisting of 30 elements.
I want the elements from 1-12 enabled , and the rest(13-30) disabled
and also once the user selects the disbaled items , the combo box should take care
of not selecting the options
How could I do this ..
Regards,
Veeresh

I doubt if this is possible. I don't think you could disable specific items in a CComboBox.

you have to subclass the CComboBox for same.. subclassing is the key to this type of effect

Hi all,
I have an application written in Visual C++6.0 which uses a Rich Edit Control to display user chat. I want to implement text highlighting as in MS Word for this rich edit control so that I can highlight messages from particular players.
I am using CHARFORMAT structure for formatting text. Can someone help me implementing this?
I tried using CHARFORMAT2 which has text BackColor property but it didnt help.
Thanking in anticipation

CHARFORMAT2 cf;
memset(&cf, 0, sizeof(CHARFORMAT2));
cf.cbSize = sizeof(CHARFORMAT2);
cf.dwMask = CFM_BOLD;
cf.dwEffects = CFE_BOLD;
COLORREF clr =RGB(255, 10, 15) ;
cf.dwMask =CFM_COLOR;
//cf.dwEffects = CFE_AUTOCOLOR; // Bold
cf.crTextColor = clr;

Hello All,
I have small and simple COM program to access a Add function in Dll and I am accessing this function from main program. For the simple add function it is working, interface and dll files are working properly.
For this interface I am trying to add one more function by name getdate() which of return Char* .. can any one please help how to declare the getdate() function in interface ???
Below are declaration and files with there names ….
// File interface.h
// This file contains interface related declarations.
#ifndef _A_INTERFACE_H_
#define _A_INTERFACE_H_
DECLARE_INTERFACE_(IMyA,IUnknown)
{
STDMETHOD_(LONG,MyAdd)(INT,INT) PURE;
};

file :- MyA.h
class CMyA : public CCmdTarget
{
DECLARE_DYNCREATE(CMyA)
CMyA();

return (x+y);
}

// function to be added to Interface can u please help me how to declare this function in interface.

struct tm *newtime;
char am_pm[] = "AM";

From the macros you're using I guess you implement the server using ATL.
Use the class wizard to add your new interface method: right click on the interface in the class view and select "Add method..." or something like that.
Hope this helps

Hi Roger,
Thanks a lot for the response.
I was waiting for a long time for the response thanks a lot.
Actually I did not use wizard for creating interface or for adding interface methods.
I manually written the code for the Add function and its working I can access the add
Function from the main function
Main function
int main (void)
{
IClassFactory *pclsf;
IUnknown *pUnk;
IMyA *pA;
int x,y;
long result;
//Initialize the OLE libraries
CoInitialize(NULL);
//get the IClassFactory interface pointer
HRESULT hr = CoGetClassObject(
MYA_CLSID,CLSCTX_INPROC,NULL,IID_IClassFactory,
(void **) &pclsf);
//USe IMyA interface for additions
printf("Input two numbers you want to add.\n");
scanf("%d\n%d",&x,&y);
result=pA->MyAdd(x,y);
The above function is working properly now I want to add one more function to interface
Which I have mentioned in the earlier post.
Can u please help me with that .. can u please tell me how to add function to interface
// file Interface.h
DECLARE_INTERFACE_(IMyA,IUnknown)
{
STDMETHOD_(LONG,MyAdd)(INT,INT) PURE;
}
no I want to add this function
har* CMyA::getDate()
{
struct tm *newtime;
char am_pm[] = "AM";

How to add this function to interface ?? please help me out …

As I see it there are two ways of implementing a COM server using ATL:
either you use the wizard provided help or you don't.
If you choose not to use the wizards, things get a little more hard but could be worth the trouble since you'll learn a lot from it.
In my opinion the best way to learn it is by actually doing it... i.e. in your situation create a dummy ATL project and make a backup of the files, then use the wizard to add an interface method and compare the files with the files in your backup copy.
Then you'll know what to do.

Hi Roger,
I am very much new to COM , I got an example in book I just went through it and created a working dll file .
There they have not used wizard for adding methods. I know how to add a new class for the project.
Can u please tell me how to add methods to interface using Wizards. ??
Thanking you..

Have a look at this article[^] in the CodeProject COM section. It describes how to create the project and add functionality to the server.
Have a look at other articles in the same section as well, CodeProject articles are a great starting point since people often tend to write about their own experiences. Try to find an article that meets your level of expertise/knowledge on the subject and startfrom there.
The article I suggested above looks suitable given how I interpreted your needs, but there might be another article that may help you better. Simply browse through the list of COM articles and judge from the heading to sort those out that you're interested in.

Hello,
is it posible to make programs with VS6(C++) for multicore cpu?
Thanks in advance
break;
|
|
|
|
|
yes, but I would advise you to use the most up to date platform SDK.
|
|
|
|

Hello,
thank you for your reply, i have the newest version of platform SDK,
are there any settings in my projectsolution to take, or how to know that my application is for
multicore cpu created?
thanks!
break;

If your app is single-threaded, then you won't get any benefit from multiple CPUs or cores. If you do create other threads, let the OS schedule the threads across the CPUs as needed.

Hello Mike,
yes, ok, i like to know for the future how to use this in programming,
and my current app is multithreaded, maybe i can make this to multicore app...when i know more about multicore programming..
regards

There's no such thing as "multicore programming" at application level. The operating system handles the details of multiple processors, multiple cores, hyperthreading, etc. If your application is multithreaded, the OS takes care of scheduling it on whatever execution units are available.

Not really a big problem since I could just rename my function, but nontheless, I would like to know how to correctly deal with this.
I have a class with a member function:
virtual HWND CreateWindow( DWORD dwStyle, HWND hWndParent );
No prizes for guessing what the derived class should do 
Upon compile, it clashes with the CreateWindow macro giving me an error:
warning C4003: not enough actual parameters for macro 'CreateWindowW'<br />
error C2059: syntax error : 'constant'
Would somebody be kind enough to help me out with this as I really really want to keep that function name.
